Psychological Typhoon Eye Effect Observed in Earthquake-Stricken People
A recent study on the psychological impact of Wenchuan earthquake on people and the interference measures showed that post-earthquake concern was at its lowest level in the most devastated areas, whereas people far from the earthquake area were more likely to have a high estimation of their post-earthquake concern.
The discovery was published in the PLoS ONE (the U.S.-based science journal Public Library of Science One) on March 23.
Researchers from the Institute of Psychology, Chinese Academy of Sciences surveyed a sample of 2,262 adults on their post-earthquake concern about safety and health from June 4 to July 15, 2008. Residents in both equke-hit areas (Sichuan and Gansu Provinces) and non-affected areas (Fujian and Hunan Provinces, and Beijing) responded to a questionnaire of 5 questions.
The questions were about the level of demand for safety measures, the worries for an outbreak of epidemics, and the need for medical and psychological workers. The conclusion of the survey was quite surprising because the post-earthquake panic decreased significantly as the level of residential devastation increased.
This phenomenon is similar to the "eye of the typhoon", or an area which has the most calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area and usually 10 km in diameter. The cyclone's lowest barometric pressure occurs in the eye. Because of the similarity with the meteorological phenomenon of the eye of a typhoon, Li Shu and his research team termed their finding the "Psychological Typhoon Eye effect": the closer to the center of the devastated areas, the less the concern about safety and health a person would feel.
This discovery is in contrary to common perception and ripple effect that the impact of an unfortunate event declines gradually as the ripple spreads from the center. The finding may have implications for psychological rescue workers to provide differentiated psychological assistance to people.
